"I think he's the best candidate among the remaining candidates to be President and I support Donald," Christie said. "I've known him for 14 years and consider him a personal friend. ... Certainly my goal as a Republican and an American is to make sure that (top Democrat contender) Hillary Clinton is defeated, and I believe Donald Trump is the best person to do that."

That was about it for politics talk on this call with WFAN, but there was a lot more M&Ms chatter.

"Let me just say this, first, I'm fine with peanut or plain," Christie said. "At the refreshment stand that I went to at the Wells Fargo Center, there were not offering peanut M&Ms. They were only offering plain."

"Why not just eat them out of bag?" Carton asked, repeating an earlier question.

"Because the bag is flimsy," Christie said. "The box is solid. And when you are an enthusiastic Notre Dame Fighting Irish fan as I am, you don't want a flimsy bag in your hand. You want a solid box in your hand."

"But it's a small bag," Carton said. "Just eat out of bag. Isn't it a waste of time?"

"No," Christie said. "Because I like to linger over my M&Ms and enjoy them, not just pour them down my mouth."

Esiason seemed to be on the verge of cracking up during the back and forth, which continued with Carton asking Christie if he preferred eating one at a time or pouring a bunch into his hand.

"It depends on what I'm doing," Christie answered. "If I'm only eating M&Ms, I'll eat them one at a time. If I'm also doing something else like at an arena watching a game, I'll eat like five or six M&Ms ... with the left hand. It's very important."

Why the left hand?

"Because when you're a guy like me, you have to shake a hands at an arena like that and you shake with your right hand and you don't want to have all of the germs that might come from shaking hands on the M&Ms," Christie said. "So you go with the left hand. You pour the box with your right hand into your left hand and then consume them from the left hand."
